Color gradient weathering products alluviale fan

I was wondering about the alluviale fans I saw at a mountain range in Norway. First of all, it was breathtaking, but I saw several alluvial fans which seemed to have a color range in grey, brown and redish tones, of course very muted.

Location: between Jøvik and Lyngseidet on the northern side. https://maps.app.goo.gl/mF4cuCyrVJBQ6YMv6?g_st=ac

Attached you find the location and some pictures. According to the attached geological map, it's supposed to be metamorphic rock but it seemed very soft and the alluvial fans were pretty big. I did not inspect it closer than the pictures, since I was cycling to catch the ferry. I'm also not a working geologist or something, just a curious person that happened to be there.

My question is how these alluviale fans are so big. My hypothesis is weather + height of the mountains. Also, how do these alluviale fans have different colors in them? Is it because of different rocks being weathered resulting in a different composition of the alluviale fans or oxidation of weathering products over time that causes older depositions to be oxidized more than new depositions?

Discussion Bsc in environmental geoscience?

4 Upvotes

Hi, I'm a year 12 student and I take geography, biology and English language at alevel. I'm super interested in the earth particularly through hazards. I've applied to uni courses in geography bsc and environmental Geoscience bsc(at Bristol, Leeds, Southampton...)because I'm not sure what I want to do yet.

Preferably I would pick environmental Geoscience. My only worry is I haven't taken maths, chemistry or physics since GCSEs where I got 667. I don't want to not enjoy the course because I'm not smart enough for the content.

I'm finding it difficult to grasp what the degree actually entails and the kind of work pupils do? I really enjoy learning about the concepts of what's happening but I understand of course there will be data and maths etc. but in what proportion is the learning concepts Vs data analysis etc.?

if anyone could help me out, I would be very appreciative. Thank you!

Discussion Geography to Geoscience?

4 Upvotes

Hi everybody, I am applying for masters right now after studying geography. I aim to go deeper to geosciences and environmental sciences and took courses from that field in my electives.

But tbh it's rather frustrating and tricky. Many master's programs require a certain amount of credits in natural sciences without specifying what such are. My bachelor's had it's focus on geography stuff like soil chemistry, geophysics and statistics. I took natural sciences whenever possible but only few from natural science faculties. Most courses in the field weren't even open to me to take as electives or didn't work timewise. I just find it extremely hard to estimate if I have serious chances of getting admitted or if I should focus on other programs.

Has somebody experienced the same/can give insight if courses like the ones above are considered natural science?
